UNITED STATES PATENT OFFIcE- GILBERT E. JONES, OF NEW YORK, N. Y.

Quom.

SPECIFICATION forming part of Letters Patent 110.377.618. dated February 7, 1888. Application filed October 28. 1886. Serial No. 217,459. (No model.) i

citizen of the United States, residing at New" York, in the county and State of New York, have invented new and useful Improvements in Quoins, of which the following is a specifi-- cation.

This invention relates to improvements in quoins; and it consists in the features pointed out in the following specification and claims, and illustrated in the accompanying drawings, in which Figure 1 is a plan view of the quoin,showing the same applied to lock up matter. Fig. 2 is a section in the plane to m, Fig. 1. Fig. 3 is a detail plan view ofa quoin, the cam being removed. Fig. 4 is a detail plan view of a quoin and cam. Fig. 5 is a side elevation of Fig. 4. Fig. 6 is a section in the plane 3 y, Fig. 4. Fig. 7 is a section in the plane 2 z, Fig. 8. Fig. 8 is a plan view of a quoin and earn, the quoin being adapted to act as a side-lock and an endlock. Figs. 9 and 10 show cams with engaging faces or corrugations. Fig. 11 shows a quoin fixed to a side-stick.

The scale of Figs. 3 to 8, both inclusive, is

larger than the scale of Figs. 1, 2, 9, 10, and 11.

Similar letters indicate corresponding parts.

In the example shown in the drawings the letter A indicates the sides of a galley.

B indicates the type or matter.

0 indicates the side-stick.

G is the quoin, which may be provided either with a side-lock,D, or with an end-lock, E. The side-lock D presses against the side-stick O to lock up the matter. The end-lock E is adapted to lock against the end of the matter.

As seen in Figs. 1, 2, and 8, the quoin maybe provided with both a side-lock, l), and an end-1ock,.E. The end-lock E is ridged or arched, so that it can pass over the side-stick 0.

The quoin G is provided with a pivot, I, on which operates. a cam, F. A handle or lugs, H H, allow of a 'ready operation of the cam. By moving or turning the cam in the proper direction the cam will press against a side A of the galley and cause the quoin to lock up the matter. I

The quoin isprovided with a stop, L, adapted to engage a stop, K, on the cam F, as seen in Figs. 4 and 8. When the stops K L arein engagement, the cam is in position to allow the quoin to be inserted into, or withdrawn from the galley. The stops K L thus offer ready means for rapid operation with the quoin, as by turning or moving the cam until its motion is arrested by the stops K, L such cam is brought into position to allow an insertion or withdrawal of the quoin. I

By fixing the lugs or handle H to the cam said lugs or handle will not become detached and the quoin will always be ready for use. It should be noticed that by having the cam provided with a handle or lugs, H, as shown in the drawings, said quoin is peculiarly adapted to serve as a galley-lock, asv said handle or lugs allow sufficient strain to be brought on the cam to lock up the matter, but not so great a strain as to split, break, or injure a galley. In the case of those quoins where a key or Wrench is used the strainexerted is sometimes so great that it may split a galley; but such accident is not likely to happen when the handle H is, as shown in the drawings, affixed to thecam. The cam may also be provided with flat or engaging faces or with corrugations M, as seen in Figs. 9 and 10, so that the cam will bite or securely sit against the surface with which it comes into contact, thus preventing accidental motion of the cam. The quoin may also be permanently secured to the sidestick, if desired, as seen in Fig. 11, so that the side-stick and quoin will not become separated.

If desired, corrugations may also be made at the side A of the galley to bite into the cam F, as seen in Fig. 9; or the cam and galley may both be corrugated, so that the galley and cam work into or engage one another, in the manner of a rack and pinion.

Heretofore it has been proposed to employ a rotating cam-shaped quoin turned by a key to lock upmatter in a chase, and such, therefore, I disclaim. It has also beenproposed to employ a combined side and end lock clamped in place by a wedge, and such I also disclaim.

What I claim as new, and desire to secure by Letters Patent, is-- 1. The quoin G, having the side-lock D and the stop L, in combination with the cam F, having faces to bear, respectively, against the side of the galley and the side-lock of the quoin, said cam being pivoted in the upper side of the quoin and provided at its edge 'with the stop K, so that when turned and the stop of said cam is brought intoengagement with the stop of said quoin, the latter, with its side-lock and the cam, can be introduced into or removed from the galley, substantially as described.

2. The quoin G, having the side-lock D and stop L, in combination with a galley, A, having the side-stick O, and the cam F, having faces to bear, respectively, against the sidelock of the quoin and the side of the galley, said cam being pivoted on the quoin and having a fixed and rigidly-attached lug, H, and an edge-stop, K, so that when turned and the stop of said cam is brought into engagement with the stop on the quoin, the latter,with its side-lock and the cam, can be introduced into or removed from the galley, substantially as described.

3. The quoin G, having the attached sideloek D, and provided with the stop Land vertical pivot I, in combination with the cam F,

25 journaled in the pivot on the upper side of the quoin and provided with the stop K, so that when rotated on said pivot to bringvits stop into engagement with the stop on the quoin, the latter, with its side-lock and the cam, can be introduced into or removed from the galley, substantially as described.

4. The quoin G, having the attached sideloek D, extending laterally from each of its sides and provided with the projecting stop L and vertical pivot I, in combination with the cam F, mounted on said pivot and having faces to bear, respectively, against the galley and the side-lock on the quoin, said cam having the stop K, so that when rotated to bring its said stop into engagement with the stop on the quoin, the quoin, with its side-lock and the cam, can be removed from the galley, substantially as described.

In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses.
